@PercideRolo It sounds like between this project, Raptor Ridge, the new solar panel installation at Stone Zoo, and the improved barns at Giraffe Savannah and Outback, ZNE has had a lot of construction projects going on at once. I wouldn't be surprised if their resources are spread thin, which may be the reason for how long this is taking.
Maby. Look like they are building access to highest area in Zoo. Probly a rope line area for visitor.
